摘要：

Benzyl disulphide has been used as an ionophore and dimethylsebacate as a plasticizer in order to develop a poly(vinyl chloride)-based membrane electrode for lead ion detection. The electrode exhibits good properties with a Nernstian slope of 29.2 +/- 1.3 mV per decade and a linear range of 2 x 10(-5)-5 x 10(-2) M for Pb(NO3)(2). The response time of the electrode was 4 min and the detection limit 1 x 10(-5) M Pb2+. The selectivity of the sensor is comparable with those reported for other such electrodes.
